  • Patent number: 9705694
    Abstract: Wi-Fi services multicast to a subnet in a software-defined network (SDN) are extended. An SDN controller centrally monitors a data plane of a Wi-Fi network. Advertisements for services within a first subnet by an advertising station are forwarded to the SDN controller. Parameters of the service of the advertising station are extracted for storage by performing deep packet inspection on the one or more packets. Queries for services within a second subnet by a querying station are also forwarded to the SDN controller. Parameters of the service of the querying station are extracted for storage by performing deep packet inspection on the one or more packets. The query for service to the advertisement matches responsive to the advertisement parameters compared to the query parameters. Responsive to matching, a set of connection parameters necessary for the querying station at the second subnet to connect to the advertising station at the first subnet is sent.

  • Publication number: 20170142207
    Abstract: A method of many-to-one auto-discovery between modules includes: a source (sender) module sends the same source-ID on all its connected ports (many). The module may not know on which port the ID is sent. A sink (receiver) module is capable of receiving IDs on its port (one). The sink port identifies the association-ID (AID) of one end of the association (between sender and receiver). The association may be established based on each module discovering the sink AID of the sender in both directions (bi-directional). Both directions may be required for the source signal to get received on a respective sink. The source signal may be sent asynchronously in each direction.

  • Patent number: 9651958
    Abstract: An electronic device includes a power supply, a ground, and an intermediate ground having a voltage less than a voltage of the power supply and greater than a voltage of the ground. The electronic device also includes an error amplifier having an input stage coupled between the power supply and the ground, and an output stage coupled between the power supply and the intermediate ground. A ballast transistor is coupled to receive an output from the error amplifier. A feedback circuit is coupled to an output of the ballast transistor to generate feedback signals, and the error amplifier operates in response to the feedback signals.

  • Patent number: 9628292
    Abstract: Wi-Fi flows are intelligently bridged in a software-defined network (SDN) controller of a wireless communication network that centrally coordinates data plane behavior. A default mode tunnels packets received at an access point to the SDN controller for layer 2 routing decisions. A bridging policy concerning bridging of specific types of traffic flows for the wireless communication network is received at the SDN. Data plane traffic flow for each of a plurality of access points distributed around the wireless communication network is centrally monitored. New data streams tunneled to the SDN controller are matched to bridging policies with deep packet inspection. Responsive to matching, the tunnel mode is converted to a bridge mode by sending a rule concerning the new data stream to the access point. As a result, subsequent packets of the new data stream are transferred at the access point without tunneling additional packets to the SDN controller).

  • Patent number: 9620127
    Abstract: Systems, computer-implemented methods, and tangible computer-readable media are provided for voice authentication. The method includes receiving a speech sample from a user through an Internet browser for authentication as part of a request for a restricted-access resource, pre-authenticating the speech sample, transmitting an authentication request to an authentication server, which compares the speech sample to a previously established speech profile associated with the user, and providing access to the restricted access resource based on the response.

  • Publication number: 20170047992
    Abstract: This disclosure relates to optical line system equipment, which enables wavelength addition for long haul transmission. The system is configured to prevent contention of wavelengths added into a multiplexer. For example, an optical wavelength combiner, such as a multiplexer, may include components that are configured to detect potential collisions between existing wavelengths and a newly added wavelength, and block the addition of the conflicting wavelength while alerting the operator.

  • Publication number: 20170034298
    Abstract: Facilitating content caching in a local network by using software-defined network (SDN) controller to centrally coordinate data plane behavior. One or more packets forwarded from a component of the plurality of network components is received because no flow has been installed at the component to instruct on how to handle the one or more packets. Responsive to a deep packet inspection identifying a request for external content, a caching server is queried on the local network to determine if the requested content is available locally. A response is received from the caching server that the requested content is not available, and in response, a first flow is installed within the local network to route copies of response packets associated with the requested content to the station. A second flow is installed within the local network to route copies of response packets associated with the requested content to the caching server. A third flow routes subsequent requests for the same content.

  • Publication number: 20160323311
    Abstract: A current physical location value associated is incorporated with a communication device as part of internet protocol (IP). An IP management component obtains current physical location information of a wireless communication device and modifies the IP address to incorporate the current physical location value corresponding to the current physical location of the communication device as part of the IP address of the communication device to prevent undesired intrusions by hackers, as communications associated with the communication device are routed to/from the communication device that is at the current physical location. If the communication device moves to a new location, the IP management component can perform a new IP address modification to modify the IP address to incorporate a new physical location value associated with the communication device.

  • Publication number: 20160132853
    Abstract: Remotely authenticating an invoice amount for a sales transaction with a merchant through a mobile device of a user using a USSD session initiated by a telecom service provider. The provider receives a transaction request of at least a mobile phone number and invoice amount from a POS machine at the merchant. The provider identifies the user from the mobile number and generates a one-time purchase ID associated with the invoice and sends the purchase ID to the user through the mobile device. The provider initiates an interactive USSD session with the user through a gateway and sends a menu with transaction details and financial account list on the user's mobile device within the session including multiple financial accounts registered to the user. The provider receives a password from the user through the session and deducts the invoice amount from a user's account and transfers the funds to the merchant.
